摘要:
随着超导磁体技术向更高性能推进,能量密度和总储能呈指数级增长。采用传统方法保护磁体变得极具挑战性,这些方法已被发挥到极限。CLIQ(Coupling Loss Induced Quench,耦合损耗诱导失超)等新技术有望提供保护先进磁体的稳健方法,但在大型磁体串或低磁场下会受到电感限制,从而导致更复杂的配置。本文提出了一种能大幅减少此限制并改善响应时间的技术:以双线方式绕制线圈,并在典型运行中串联连接,同时在保护情况下提供反并联连接以实现准零电感。这允许极高的di/dt。随后在一个小型REBCO线圈上演示了该概念。
英文摘要:
As superconducting magnet technology is pushed towards higher performance, energy density and total stored energy follow exponentially. Protecting magnets becomes substantially more challenging with traditional methods being stretched to their limits. New technologies such as CLIQ (Coupling Loss Induced Quench) promise to provide a robust method to protect advanced magnets, however they become inductance limited in large magnet strings or at low field, leading to more complex configurations. A technique to substantially reduce this limitation and improve response time is presented, by winding coils in a bifilar fashion and connecting them in series for typical operation, while providing an anti-parallel connection for quasi-zero-inductance in a protection case. This allows for extremely high di/dt. The concept is then demonstrated on a small REBCO coil.
